Game and Watch: Squish - Multiscreen

Squish is a Multi Screen Game & Watch video game released in 1986 by Nintendo. The game was never released in Japan. A Pocketsize version of the game was also released. The unit's model number was MG-61. In the game you have to avoid the platforms that are coming towards the player character, Ziggy the Mazeman. The game's name comes from the fact that you'll be "squished" if a platform hits you. The top screen contained game information, while all of the action took place on the bottom screen. This and Zelda were the only two games to have a format like this when it came to Multi Screen games.
